Addressing energy efficiency in P2P services has the potential to make the Internet greener since they comprise a major source of the Internet data traffic. In this paper, we consider approaches for green Internet file sharing. We develop simulation models of proxy-based energy efficient BitTorrent as well as legacy BitTorrent on PeerSim P2P simulator, and explore their characteristics on large...

Abstract: The ICT industry is quickly becoming a very significant consumer of global energy. This energy usage clearly comes at an environmental cost, and recent reports estimate that the industry now contributes 2% of the worlds CO2 emissions, or as much as the aviation industry. A significant part of this energy consumption can be attributed to data-centres, where huge numbers of energyintens...

This paper represents a full paper submission to ISTAS’2008. As an increasingly popular medium by which to access health promotion information, the Internet offers significant potential to promote (often individualized) health-related behavioral change across broad populations. Interactive online health promotion interventions are a key means, therefore, by which to empower individuals to make ...

From a village in rural Ghana, Dr. John Afele has studied in Belgium, Japan and Canada. He has traveled further on development missions and for conferences, for instance as a Board member of Global Knowledge for Development. Serving as a North-South bridge person in worldwide knowledge networks through the Internet also qualifies him for the book’s theme. His focus is on innovative ways to brid...

One unintended eeect of the growth of the Internet is increased energy usage by servers and the infrastructure supporting them. This paper promotes a research agenda to improve the energy eeciency of Internet server sites. This goal is timely as the costs of energy usage and our vulnerability to energy supply disruptions become increasingly evident. In particular, we propose energy-conscious se...
